SCRIBBLER OR CARDING-ENGINE.

SPECIFICATION formingpart of Letters Patent No. 521,703, dated June 19, 1894. Applicaticrfilecl December 12,1893- Serial No. 493,514.. (No model.)

To all whom it may concern:

Be it known that we, ERNEST CROWTHER and WILLIAM HENRY CRowTHER, subjects of the Queen of Great Britain, residing at Pudsey,

in the county of York, England,have inventsigned to insure the cleaning of the workers or card covered rollers of such machines.

It consists of an improved arrangement of the workers and of the combination therewith of other card covered rollers or brushes whereby the accumulation of grease and dirt on the workers is in a great measure prevented and consequently the labor of keeping said workers clean is materially lessened.

To clearly explain our invention weillustrate it in the accompanying drawings, in

which Figure 1 is a diagrammatic'view of a single cylinder scribbler constructed according to our invention. Fig. 2 is a similar view of a double cylinder scribbler, andvFig. 3 is a view illustrating a modification.

It will be seen that instead of as heretofore arranging around the main cylinder 1 (Fig. 1)' first a worker, then a stripper, .then another worker and then another stripper and so on, we arrange the workers 2, 2, so that they are in contact with each other and .also with the main cylinder, the centers of said workers being in an are of a circle drawn from the center of the main cylinder and in the angle or space above the workers where the circumferences of the workers converge we place, either in all of such spaces or preferably in alternate spaces a card covered and in contact with each pair of workers, and are provided with straight card teeth, shaped to fit the interstices between the workers for the purpose of cleaning the same.

, It is preferred to have the cleaners arranged in alternate spaces for the reason that then each worker is acted on by the cleaner,

and yet'there are only half as many cleaners 1 used as would be required to put one in each of said spaces above the workers.

It will be seen that the mass of fiber 5 is carried partially round each worker 2 and is then removed therefrom by the next worker which rotates in the same direction and so passes through the machine until it is removed by a stripping roller 6 as shown in Fig. 1 or by a fly comb 6 as shown in Fig. 2 which is an illustration of a scribbler having two cylinders 1. l. and provided with our improvements. 7 1

What we claim isa 1. The combination with a scribbler or card ing engine having a number of workers touching each other, arranged around the main drum of cardcovered cleaners, arranged above the workers, projecting into the angle where the circumferences of the workers converge, and in contact each with its two adjacent workers, for the purpose of cleaning the same, substantially as described.

2. The combination with a scribbler or carding engine, having a number of workers touching each other, arranged around the main 8o drum, of card covered rollers projecting into the alternate angles or spaces Where the circumferences of the workers converge, are ranged above the workers and in contact each with its two adjacentworkers, for the purpose
